All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It should be understood that the term "and/or" as used herein is merely one type of association that describes an associated object, meaning that three relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

It should be understood that although the terms first, second, third, fourth, etc. may be used to describe color pixels in embodiments of the present invention, the color pixels should not be limited to these terms. These terms are only used to distinguish color pixels from each other. For example, a first color pixel may also be referred to as a second color pixel, and similarly, a second color pixel may also be referred to as a first color pixel, without departing from the scope of embodiments of the present invention.

It should be noted that the terms "upper", "lower", "left", "right", and the like used in the description of the embodiments of the present invention are used in the angle shown in the drawings, and should not be construed as limiting the embodiments of the present invention. In addition, in this context, it is also to be understood that when an element is referred to as being "on" or "under" another element, it can be directly formed on "or" under "the other element or be indirectly formed on" or "under" the other element through an intermediate element.

Before explaining the present invention in detail, a display principle of the display panel according to the present embodiment is briefly introduced, as shown in fig. 1, which is a schematic structural diagram of the display panel according to the present embodiment of the invention, and the display panel 100 according to the present embodiment may be understood as a liquid crystal display panel, where the liquid crystal display panel includes an array substrate 62 and a color filter substrate 61 that are oppositely disposed, and a liquid crystal layer 63 located between the array substrate 62 and the color filter substrate 61. A plurality of pixels (not shown) defined by a plurality of rows of gate lines (not shown) and a plurality of columns of data lines (not shown) crossing each other are disposed on the array substrate 62, and a thin film transistor (not shown), a pixel electrode (not shown) and a common electrode (not shown) are disposed in each pixel. The grid electrode of each thin film transistor is connected with a grid line, the source electrode of each thin film transistor is connected with a data line, and the drain electrode of each thin film transistor is connected with a pixel electrode. And under the control of the corresponding grid line, the data line corresponding to the source electrode of the thin film transistor charges and discharges to the pixel electrode corresponding to the drain electrode through the thin film transistor, and an electric field is formed between the pixel electrode and the common electrode. When the liquid crystal display panel displays, the common electrode receives a common electrical signal (usually a constant voltage signal), an electric field is formed between the pixel electrode and the common electrode, and the deflection of liquid crystal molecules in the liquid crystal layer is controlled, so that light in the backlight source is transmitted out to achieve the display function.

In the prior art, no matter what the arrangement of the pixels, when the display panel presents a pure color picture, for example, a red picture is displayed, when all red pixels of the display panel need to be changed from one signal (for example, when the deflection angle of the liquid crystal molecules is α) to another signal (when the deflection angle of the liquid crystal molecules is α), the change can be called polarity inversion. If the liquid crystal molecules are always in a fixed and unchangeable electric field for a long time, the characteristics of the liquid crystal molecules (the liquid crystal molecules rotate along with the change of the electric field) are damaged, part of liquid crystal molecules do not respond to the change of the electric field too much, so that the deflection angles of part of the liquid crystal molecules are not accurate, the light transmission quantity of part of the liquid crystal molecules is different, and the picture brightness of the liquid crystal molecules after deflection is different.

In order to solve the technical problems, the inventor designs the following technical scheme:

Similarly, the color of the pixels included in the second pixel column 1302 is the same as the color of the pixels included in the fourth pixel column 1304, and for understanding the second pixel column 1302 and the fourth pixel column 1304, reference may be made to understanding of the first pixel column 1301 and the third pixel column 1303, and details are not repeated here.

The display panel 100 further includes N data output terminal groups 19 corresponding to the N driving unit groups 17, each data output terminal group 19 includes a first data output terminal 191 and a second data output terminal 192, and the polarity of the data signal output from the first data output terminal 191 is opposite to the polarity of the data signal output from the second data output terminal 192.

It should be added that, for example, as shown in fig. 2, the polarity of the data signal output by the first data output terminal 191 is positive, and the polarity of the data signal output by the second data output terminal 192 is negative, in fact, or the polarity of the data signal output by the first data output terminal 191 may also be negative, and the polarity of the data signal output by the second data output terminal 192 is positive. In this embodiment, the polarities of the data signals output by the two data output terminals are not limited, as long as the polarity of the data signal output by the first data output terminal is opposite to the polarity of the data signal output by the second data output terminal.

As shown in fig. 2, wherein the second ends of the two switch set elements 170 in the first driving unit 171 are electrically connected to the first data output end 191, and the two pixel columns corresponding to the two switch set elements 170 connected to the first data output end 191 have different pixel colors, the second ends of the other two switch set elements 170 in the first driving unit 171 are electrically connected to the second data output end 192, and the two pixel columns corresponding to the other two switch set elements 170 connected to the second data output end 192 have different pixel colors; the second ends of the two switch set elements 170 in the second driving unit 172 are electrically connected to the first data output end 191, and the two pixel columns corresponding to the two switch set elements 170 connected to the first data output end 191 have different pixel colors, the second ends of the other two switch set elements 170 in the second driving unit 172 are electrically connected to the second data output end 192, and the two pixel columns corresponding to the other two switch set elements 170 connected to the second data output end 192 have different pixel colors; wherein, N is more than or equal to 1 and is a positive integer.

The polarity of the data signal according to the present embodiment is briefly described as follows:

in the display panel, during the display process, the deflection of the liquid crystal molecules is determined by a common voltage signal received by the common electrode and a data signal received by the pixel electrode. Since the common electrode usually receives a constant electrical signal (for example, the voltage value of the constant electrical signal is a), it can be understood that, when the voltage value b of the data signal received by the pixel electrode is greater than the voltage value a of the common electrical signal received by the common electrode, the polarity of the data signal is positive, that is, the polarity of the data signal received by the corresponding pixel is positive, whereas the polarity of the data signal is negative, and the polarity of the data signal received by the corresponding pixel is negative. It should be emphasized that, for the display of a pure color image, for example, when a red image is displayed, the polarity of the data signal received by a part of the red pixels may be positive, the polarity of the data signal received by a part of the red pixels may be negative, and in this case | b-a | is a constant value, so as to ensure that the amount of light transmitted from the liquid crystal molecules is the same, and to ensure the stability of the display image. For example, if a is 5V, the data signal b received by the partial red pixel is 0V, and the data signal b received by the partial red pixel is 10V, at this time, the liquid crystal molecules are deflected at the same angle, except that a part of the liquid crystal molecules are deflected clockwise and a part of the liquid crystal molecules are deflected counterclockwise, and since the deflection angle value of the liquid crystal molecules is constant, the amount of light transmitted from the backlight is constant, and the display of the screen is not affected.

Also, it is understood that clockwise deflection of the liquid crystal molecules corresponds to a positive polarity and counterclockwise deflection of the liquid crystal molecules corresponds to a negative polarity. That is to say, in the process of displaying a pure color picture, the pixels of the same color are divided into two parts, wherein the polarity of the data signal received by one part is positive, and the polarity of the data signal received by the other part is negative, so that in the process from the first time period of polarity inversion to the second time period of polarity inversion, the polarity of the data signal received by the pixels of the same color is partly positive and partly negative, thereby avoiding the flicker phenomenon caused by the obvious brightness inconsistency due to the change of the whole picture from one polarity to the other polarity, and improving the display quality. Although the polarities are different, the deflection angle of the liquid crystal is the same, and thus, the display is not affected.

It should be added that "the polarity inversion first time period" may be understood as a frame time, "the polarity inversion second time period" may be understood as a frame time, and "the polarity inversion first time period to the polarity inversion second time period" may be understood as a frame time from the current frame to the next frame. The polarity of the data signal output by the first data output end of the current frame is opposite to that of the data signal output by the first data output end of the next frame.

In this embodiment, in the process of displaying a pure color picture, in the display panel 100, assuming that the first color pixel 1011 is a red pixel, in combination with the arrangement shown in fig. 2, the polarity of the data signal provided to each red pixel when displaying the red picture is as shown in fig. 3, fig. 3 is another structural schematic diagram of the display panel provided in the embodiment of the present invention, in one pixel column unit group 13, the polarities of the data signals received by two red pixel columns (the first pixel column 1301 and the third pixel column 1303) in the first pixel column unit 131 are opposite, that is, the polarity of the data signal received by the first pixel column 1301 is positive, and the polarity of the data signal received by the third pixel column 1303 is negative.

The exemplary process of polarity inversion in this embodiment is described by taking a polarity inversion period as one frame, specifically:

under the current frame, the polarity part of the data signal received by the red pixel is positive, and the polarity part of the data signal is negative; in the next frame, the polarity of the data signal received by the part of the red pixels receiving the data signal with the positive polarity becomes negative, and the polarity of the data signal received by the part of the red pixels receiving the data signal with the negative polarity becomes positive, that is, when the current frame is shifted to the next frame (two adjacent frames of pictures are switched), the polarity of the data signal received by the part of the red pixels is changed from the first signal (which can be understood as the polarity of the data signal is positive) to the second signal (which can be understood as the polarity of the data signal is negative), and the polarity of the data signal received by the other part of the red pixels is changed from the second signal (which is the polarity of the data signal is negative) to the first signal (which is the polarity of the data signal is positive). In other words, because the polarity of the data signal received by the pixels of the same color in each frame is positive and negative, the present embodiment can avoid the flicker phenomenon caused by the apparent brightness difference when the whole frame is changed from one polarity to another polarity when the two adjacent frames are switched, and improve the display effect. Compared with the prior art, the display area has the advantages that the flicker phenomenon when the data signals received by the pixels of the same color in the whole display area are all changed from one polarity to the other polarity when the pictures of two adjacent frames are switched is avoided, and the display quality is improved.

It should be noted that the first data output terminal 191 and the second data output terminal 192 included in the data output terminal group 19 according to the present embodiment are both driven by a driving chip, that is, the data signal received by the pixel is provided by the driving chip.

According to the structure of the display panel shown in fig. 2, the present embodiment provides a driving method of a display panel, which is applicable to the display panel 100 described above.

As shown in fig. 4, which is a flowchart of a driving method of a display panel according to an embodiment of the present invention, the driving method of the display panel includes:

providing data signals with opposite polarities to a first data output end and a second data output end;

and step two, providing an enabling signal for the switch group element, conducting the first end and the second end of the switch group element, and transmitting the data signal to the corresponding pixel column.

The driving method of the display panel is exemplarily described by taking the first color pixel 1011 shown in fig. 2 as an example:

in the current frame, the polarity of the data signal output by the first data output terminal 191 is positive, and the polarity of the data signal output by the second data output terminal is negative, at this time, in the first pixel column unit 131, the polarities of the data signals received by the first pixel column 1301 and the second pixel column 1302 which are respectively and electrically connected to the first data output terminal 191 are both positive, that is, the polarity of the data signal received by the first color pixel 1011 arranged on the first pixel column 1301 is positive, and the polarities of the data signals received by the third pixel column 1303 and the fourth pixel column 1304 which are respectively and electrically connected to the second data output terminal 192 are negative, that is, the polarity of the data signal received by the first color pixel 1011 arranged on the third pixel column 1303 is negative; similarly, in the second pixel column unit 132, the polarities of the data signals received by the first pixel column 1301 and the second pixel column 1302 which are electrically connected to the first data output end 191 respectively are both positive, at this time, the polarity of the data signal received by the first color pixel 1011 disposed on the first pixel column 1301 is positive, the polarities of the data signals received by the third pixel column 1303 and the fourth pixel column 1304 which are electrically connected to the second data output end 192 respectively are both negative, and the polarity of the data signal received by the first color pixel 1011 disposed on the third pixel column 1303 is negative. That is, in the current frame, for the first color pixel 1011, the polarity of the partially received data signal is positive, and the polarity of the partially received data signal is negative.

In the next frame, the polarity of the data signal output from the first data output terminal 191 becomes negative, and the polarity of the data signal output from the second data output terminal 192 becomes positive. At this time, in the first pixel column unit 131, the polarities of the data signals received by the first pixel column 1301 and the second pixel column 1302 which are electrically connected to the first data output terminal 191 respectively are both negative, the polarity of the data signal received by the first color pixel 1011 disposed on the first pixel column 1301 is negative, the polarity of the data signal received by the third pixel column 1303 and the fourth pixel column 1304 which are electrically connected to the second data output terminal 192 respectively is positive, and the polarity of the data signal received by the first color pixel 1011 disposed on the third pixel column 1303 is positive; similarly, in the second pixel column unit 132, the polarities of the data signals received by the first pixel column 1301 and the second pixel column 1302, which are electrically connected to the first data output terminal 191, are also negative, at this time, the polarity of the data signal received by the first color pixel 1011 disposed on the first pixel column 1301 is negative, the polarity of the data signal received by the third pixel column 1303 and the fourth pixel column 1304, which are electrically connected to the second data output terminal 192, is positive, and the polarity of the data signal received by the first color pixel 1011 disposed on the third pixel column 1303 is positive. That is, at the next frame, for the first color pixel 1011, the polarity of the partially received data signal is positive, and the polarity of the partially received data signal is negative, so as to ensure that the polarity of the partially received data signal is changed from positive to negative and the polarity of the partially received data signal is changed from negative to positive during the display process from the current frame to the next frame, thereby avoiding the flicker phenomenon occurring when the data signals received by the pixels of the same color are all changed from one polarity to the other polarity in the whole display area when the pictures of two adjacent frames are switched.

Further, as shown in fig. 5, fig. 5 is another schematic structural diagram of the display panel according to the embodiment of the present invention, in which one first pixel column unit 131 and one second pixel column unit 132 in each pixel column unit group 13 in the embodiment are arranged at intervals in the row direction, and the polarities of the data signals received by the pixels of the same color in the same row are the same. Taking the pixel arrangement shown in fig. 5 as an example, still taking the first color pixel 1011 as an example, the polarity of the data signal received by the first color pixel 1011 in the first row is positive, and the polarity of the data signal received by the first color pixel 1011 in the second row is negative, and in the row direction, the polarities of the received data signals are arranged alternately, so that the polarity arrangement is uniform, further reducing the flicker of the whole picture in the polarity inversion process, and making the display effect of the display panel better.

Inevitably, in order to further reduce flicker and improve display quality, the pixels of the same color in the present embodiment receive the same number of data signals with positive polarity as the number of data signals with negative polarity.

In addition, in the process of displaying the local pure color of the display panel, since the polarities of the data signals received by the two pixel rows containing the pixels with the same color in each pixel row unit are different, as shown in fig. 5, taking the first color pixel 1011 in the first pixel row unit 131 as an example, the polarities of the data signals received by the first pixel row 1301 and the third pixel row 1303 are opposite, so that the flicker phenomenon caused in the process of polarity inversion can be avoided.

Further, taking the pixel arrangement shown in fig. 5 as an example, for exemplarily giving the polarity of the data signals of the pixels in each pixel column, since the color of the pixel included in the first pixel column 1301 is the same as the color of the pixel included in the third pixel column 1303, the color of the pixel included in the second pixel column 1302 is the same as the color of the pixel included in the fourth pixel column 1304, and the colors of the pixels in the two pixel columns corresponding to the two switch group elements 170 connected to the first data output end 191 are different in the same driving unit, the connection relationship between the driving unit and the pixel column unit group is as follows:

first, as shown in fig. 2, the data line 150 electrically connected to the first pixel column 1301 and the data line 150 electrically connected to the second pixel column 1302 in the first data line unit 151 are electrically connected to the first data output terminal 191 through the respective switch set elements 170, and the data line electrically connected to the third pixel column 1303 and the data line electrically connected to the fourth pixel column 1304 are electrically connected to the second data output terminal 192 through the respective switch set elements 170.

In one pixel column unit, polarities of data signals received by different pixel columns corresponding to the same color pixel are opposite, and for example, taking the first color pixel 1011 in the first pixel column unit 131 shown in fig. 2 as an example, the polarity of the data signal received by the first pixel column 1301 is positive, and the polarity of the data signal received by the third pixel column 1303 is negative, so that in the frame inversion process of a local pure color picture, the polarity of the data signal received by the same color pixel is changed from positive to negative, and the polarity of the data signal received by a part of the same color pixel is changed from negative to positive, thereby avoiding the flicker phenomenon.

Second, as shown in fig. 5, the data line electrically connected to the first pixel column 1301 and the data line electrically connected to the fourth pixel column 1304 in the first data line unit 151 are electrically connected to the first data output terminal 191 through the respective switch set elements 170, and the data line electrically connected to the second pixel column 1302 and the data line electrically connected to the third pixel column 1303 are electrically connected to the second data output terminal 192 through the respective switch set elements 170. When two adjacent frames of pictures of the display panel are switched, the polarity of the data signal received by the pixel part of the same color is changed from positive to negative, and the polarity of the data signal received by the pixel part of the same color can be changed from negative to positive, so that the occurrence of flicker can be effectively avoided, and the display effect is improved. In addition, the positive polarity and the negative polarity of the data signals received by the pixel electrodes of the same color are uniformly arranged in the row direction or the column direction, so that the flicker is further reduced, and the display quality is improved.

Based on the two connection manners, in an embodiment, the display panel of this example further includes four clock signal line groups, and the corresponding connection relationship between the four signal line groups and the data line unit groups may be varied, for example, as shown in fig. 6, which is another structural schematic diagram of the display panel provided in this embodiment of the invention, the display panel 100 in this embodiment further includes four clock signal line groups, which are respectively the first clock signal line group CK1, the second clock signal line group CK2, the third clock signal line group CK3, and the fourth clock signal line group CK 4; the control terminals 1701 of the four switch group elements electrically connected to the first data output terminal 191 are electrically connected to the four clock signal line groups in a one-to-one correspondence, respectively, and the control terminals 1701 of the four switch group elements electrically connected to the second data output terminal 192 are also electrically connected to the four clock signal line groups in a one-to-one correspondence, respectively. In the process of charging the pixels in the same row, after the four clock signal lines are sequentially turned on, the four switch group elements 170 electrically connected to the first data output terminal 191 transmit the data signals to the corresponding four pixel columns, and the four switch group elements 170 electrically connected to the second data output terminal 192 transmit the data signals to the corresponding four pixel columns, thereby completing the charging of the first pixel column unit 131 and the second pixel column unit 132 included in one pixel column unit group 13. Although each row comprises N pixel column unit groups, the connection relation in each pixel column unit group is the same, so that the charging process of pixels in one row can be completed only by four clock signal line groups, and the charging time of the pixels in the same row is saved.

Further, in a specific embodiment, with continuing reference to fig. 6, 8, 9 and 10, fig. 8, 9 and 10 are schematic structural diagrams of a display panel provided by an embodiment of the present invention, and the control terminals 1701 of the four switch group elements 170 corresponding to the four data lines 150 in the first data line unit 151 are electrically connected to the four clock signal line groups in a one-to-one correspondence manner; the control terminals 1701 of the four switch group elements 170 corresponding to the four data lines 150 in the second data line unit 152 are electrically connected to the four clock signal line groups in a one-to-one correspondence.

Taking the structure of the display panel shown in fig. 6, the first color pixel 1011 is taken as an example, and a specific driving method thereof is described:

as shown in fig. 7, which is a timing diagram of the display panel according to the embodiment of the present invention, fig. 7 is a timing diagram of the first color pixels 1011 shown in fig. 6 receiving data signals, and in combination with the structure of the display panel shown in fig. 6, the display panel 100 further includes a plurality of gate lines 23, one gate line 23 is electrically connected to one row of pixels, for example, the first row of pixels corresponds to the first gate line 231, and the second row of pixels corresponds to the second gate line 232. In this example, the scanning time of each two adjacent gate lines 23 is a period G, the scanning time of the previous gate line is a first sub-period G1, and the scanning time of the next gate line is a second sub-period G2; the first sub-period G1 and the second sub-period G2 each include four time periods, t1, t2, t3, and t4, respectively.

The driving method of the display panel comprises the following steps:

during the first sub-period G1, a data signal is supplied to the first data output terminal 191, and enable signals are supplied to the four clock signal line groups, respectively;

during the second sub-period G2, the data signal is supplied to the second data output terminal, and the enable signals are supplied to the four clock signal line groups, respectively.

The above driving method is explained as follows:

in the first sub-period G1, that is, in the period of scanning the first gate line 231, in the first period t1, the first clock signal line group CK1 provides the enable signal to the switch group element 170 corresponding to the third pixel column 1303 in the corresponding first pixel column unit 131, so that the first terminal and the second terminal of the switch group element 170 are turned on, but at this time, since the second data output terminal 192 is not turned on, no corresponding signal is transmitted to the third color pixel 1013 in the first pixel column unit 131; meanwhile, the first clock signal line group CK1 provides an enable signal to the switch set element 170 corresponding to the second pixel column 1302 in the corresponding second pixel column unit 132, so that the first terminal and the second terminal of the switch set element 170 are turned on, and at this time, no corresponding data signal is transmitted to the second color pixel 1012 in the second pixel column unit 132 because the first data output terminal 191 is not turned on. During the second time period t2, the second time signal line group CK2 is turned on, and the corresponding electrical connection switch group element 170 is turned on, at this time, no corresponding signal is transmitted to the fourth color pixel 1014 in the first pixel column unit 131 because the second data output terminal 192 is not turned on; at this time, the first data output end 191 is turned on, so that the data signal with the positive polarity can be transmitted to the first color pixel 1011 in the corresponding second pixel row unit 132. The transmission process of the data signal in the third time period t3, the fourth time period t4, and the second sub-period G2 is similar, and will not be described herein again.

In this example, in the current frame, the polarity of the data signal received by the corresponding portion of the first color pixel 1011 is positive, and the polarity of the data signal received by the corresponding portion is negative, and in the next frame, the gate lines of each row are scanned in the same manner as described above, except that the polarity of the data signal output from the first data output terminal 191 to the corresponding pixel is negative, and the polarity of the data signal output from the second data output terminal 192 to the corresponding pixel is positive. Still taking the first color pixel 1011 as an example, the polarity of the data signal received by the first color pixel 1011 is changed from positive to negative, and the polarity of the data signal received by the first color pixel 1011 is changed from negative to positive, so that in the process of switching between two adjacent frames, it is ensured that the polarity of the data signal received by the same color pixel is changed from positive to negative partially and from negative to positive partially, thereby improving the flicker phenomenon and improving the display quality of the display panel.

In addition, in this embodiment, the data lines connected to the pixels of the same color in the same row are respectively connected to different clock signal line groups, so that when the display panel displays a pure color picture, the data lines are turned on in a time-sharing manner, so that the pixels of the same color are charged in a time-sharing manner, thereby avoiding the problem of mutual interference caused by simultaneous charging of the pixels of the same color, and ensuring the display effect.

It should be noted that, in the structures of the display panels shown in fig. 8 to fig. 10, the manner of scanning each row of gate lines is the same, that is, the scanning of one gate line can be completed by sequentially turning on four clock signal line groups. The difference is that, for a specific color, the corresponding clock signal line group and the corresponding data output terminal are simultaneously turned on, and then the corresponding polarity signal is transmitted to the corresponding pixel. Therefore, in the process of polarity inversion from the current frame to the next frame, part of the polarity of the received data signals changes from positive to negative, and part of the polarity of the received data signals changes from negative to positive, so that the flicker phenomenon is avoided.

In addition, the display panels shown in fig. 8 to 10 may be respectively connected to different clock signal line groups through data lines connected to pixels of the same color in the same row, so that when the display panel displays a pure color image, the pixels of the same color are turned on in a time-sharing manner, so that the pixels of the same color are charged in a time-sharing manner, thereby avoiding the problem of mutual interference caused by simultaneous charging of the pixels of the same color, and ensuring the display effect.

Still further, in one embodiment, during the first sub-period, the polarity of the data signal provided to the first data output terminal is positive, and during the second sub-period, the polarity of the data signal provided to the second data output terminal is negative;

or, in the first sub-period, the polarity of the data signal provided to the first data output terminal is negative, and in the second sub-period, the polarity of the data signal provided to the second data output terminal is positive.

In this example, the first sub-period corresponds to a scanning segment of one gate line, the second sub-period corresponds to a time period of scanning of another gate line, and the time required for completing scanning of the gate lines included in the entire display panel can be understood as the time of one frame, so that it can be obtained that, in one frame time, the polarity of the data signal output by the first data output segment is opposite to the polarity of the data signal output by the second data output end, so that it can be ensured that, in the current frame, the polarity of the data signal received by the pixels of the same color is partially positive and partially negative, and further, in the next frame, the polarity of the data signal is partially positive and partially negative, and the flicker phenomenon is avoided.

In another specific implementation, as shown in fig. 11 and 13, fig. 11 and 13 are schematic structural diagrams of a display panel according to an embodiment of the present invention, wherein the control terminals 1701 of the four switch group elements 170 corresponding to the four data lines 150 in the first data line unit 151 are electrically connected to two clock signal line groups; the control terminals 1701 of the four switch group elements 170 corresponding to the four data lines 150 in the second data line unit 152 are electrically connected to the other two clock signal line groups. For convenience of description, four switch group elements in the driving unit are named, namely, a switch group element 170A, a switch group element 170B, a switch group element 170C, and a switch group element 170D.

The following describes the connection relationship of this embodiment in detail by taking the display panel shown in fig. 11 as an example: of the four switch group elements corresponding to the four data lines 150 in the first data line unit 151, the control terminals 1701 of the switch group element 170A and the switch group element 170B are connected to the first clock signal line group CK1, and the control terminals 1701 of the switch group element 170C and the switch group element 170D are connected to the second clock signal line group CK 2; of the four switch group elements corresponding to the four data lines in the second data line unit 152, the control terminals 1701 of the switch group element 170A and the switch group element 170B are connected to the third clock signal line group CK3, and the control terminals 1701 of the switch group element 170C and the switch group element 170D are connected to the fourth clock signal line group CK 4.

Taking the structure of the display panel shown in fig. 11, the first color pixel 1011 is taken as an example, and a specific driving method thereof is described:

as shown in fig. 12, which is a timing diagram of the display panel according to the embodiment of the invention, fig. 12 is a timing diagram of the first color pixels 1011 shown in fig. 11 receiving data signals, and in conjunction with the structure of the display panel shown in fig. 11, the display panel 100 further includes a plurality of gate lines 23, one gate line 23 is electrically connected to one row of pixels, for example, the first row of pixels corresponds to the first gate line 231, and the second row of pixels corresponds to the second gate line 232. In this example, the scanning time of each two adjacent gate lines 23 is a period G, the scanning time of the previous gate line is a first sub-period G1, and the scanning time of the next gate line is a second sub-period G2; the first sub-period G1 and the second sub-period G2 each include four time periods, t1, t2, t3, and t4, respectively.

The driving method of the display panel comprises the following steps:

in the first sub-period G1, providing a data signal to the first data output terminal 191, providing enable signals to the four clock signal line groups, respectively;

The specific explanation is as follows:

in the first sub-period G1, that is, the period of time when the first gate line 231 scans, the first data output terminal 191 is provided with a data signal in the first time period t1, and when the first clock signal line group CK1 is turned on, the first data output terminal 191 is provided with an enable signal to the switch group element 170A corresponding to the first pixel column 1301 and the switch group element 170B corresponding to the second pixel column 1302 in the corresponding first pixel column unit 131, so that the first and second terminals of the switch group element 170A and the switch group element 170B are turned on, but since the switch group element 170A corresponding to the first pixel column 1301 is electrically connected to the first data output terminal 191 and the second data output terminal 192 electrically connected to the switch group element 170B corresponding to the second pixel column 1302 is not turned on, only the data signal with positive polarity output by the first data output terminal 191 is transmitted to the first color pixel 1011; similarly, during the second time period t2, although the clock signal line group CK2 is turned on, the first data output terminal 191 and the second data output terminal 192 are not turned on, and thus no corresponding data signal with positive or negative polarity is transmitted to the corresponding pixel, until the third time period t3, the data signal with positive polarity output from the first data output terminal 191 is not transmitted to the first color pixel 1011 in the second pixel column unit 132. In the fourth time period t4, the data signal with the positive polarity output by the first data output terminal 191 is not transmitted to the corresponding pixel, and the data signal with the negative polarity output by the second data output terminal 192 is not transmitted to the corresponding pixel.

During the second sub-period G2, i.e., the period of time when the second gate line 232 scans, during the first period t1, although the first clock signal line group CK1 provides the enable signal to make the first terminal and the second terminal of the corresponding switch group element conductive, the first data output terminal 191 and the second data output terminal 192 do not work, and do not output the data signal with the positive or negative polarity to the corresponding pixel; a second time period t2, in which a data signal is supplied to the second data output terminal 192 and an enable signal is supplied to the second clock signal line group CK2, so that a data signal with a negative polarity output from the second data output terminal 192 is transmitted to the corresponding first color pixel 1011; the third time period t3 is similar to the first time period t1, and the fourth time period t4 is similar to the second time period, which is not repeated herein.

Therefore, after the gate line 23 of the whole display panel is scanned, that is, when the current frame is completed, the polarity of the data signal received by the first color pixel 1011 is partly positive and partly negative, and in the next frame, the scanning mode of the gate line 23 of the display panel is the same as that of the previous frame, except that the polarity of the data signal output by the first data output terminal 191 is changed from positive to negative, and the polarity of the data signal output by the second data output terminal 192 is changed from negative to positive, so that the polarity of the data signal received by the first color pixel 1011 is changed from positive to negative and partly negative to positive, thereby avoiding the flicker phenomenon and improving the display quality of the display panel.

It should be noted that the driving method of the display panel shown in fig. 13 is similar to the driving method of the display panel shown in fig. 11, and only when the data output terminal and the corresponding clock signal line group are both turned on, the data signal with positive or negative polarity is transmitted to the corresponding pixel. Therefore, the pixel of the same color can still realize that the polarity of the data signal received by the pixel of the same color is partially positive and partially negative in the polarity of the data signal received by the current frame, so that the polarity of the data signal received by the pixel of the same color is partially changed from positive to negative and partially changed from negative to positive in the polarity inversion process of the next frame, and the flicker phenomenon is avoided.

In one embodiment, as shown in fig. 14, which is another schematic structural diagram of the display panel provided in the embodiment of the present invention, each clock signal line group includes one clock signal line, that is, the first clock signal line group CK1 includes one clock signal line CK11, the second clock signal line group CK2 includes one clock signal line CK12, the third clock signal line group CK3 includes one clock signal line CK13, and the fourth clock signal line group CK4 includes one clock signal line CK 14. Each switch group element 170 includes one switch element 1711, and the control terminals 1701 of the four switch elements 1711 electrically connected to the first data output terminal 191 are electrically connected to the four clock signal lines in a one-to-one correspondence, respectively, and the control terminals 1701 of the four switch elements 1711 electrically connected to the second data output terminal 192 are electrically connected to the four clock signal lines in a one-to-one correspondence, respectively.

Because the data signals corresponding to the pixels with different colors are different, the data signals output by the data output end are different, and the normal display function can be realized only by outputting different data signals according to different colors in a time-sharing manner, so that the condition that the same data signal is input to different color pixels at the same time to influence the display is avoided.

Further, the switching element 1711 in this embodiment is an N-type thin film transistor or a P-type thin film transistor. When the N-type thin film transistor is selected, the clock signal line group outputs a high level signal to control the switch element 1711 to be turned on; when the P-type thin film transistor is selected, the constant signal line group outputs a low-level signal to control the switch element 1711 to be turned on. In fig. 14, only the case where the switching element 1711 is an N-type thin film transistor will be described.

In another embodiment, as shown in fig. 15, which is another schematic structural diagram of the display panel provided in the embodiment of the present invention, each clock signal line group 21 in the embodiment includes two clock signal lines, that is, the first clock signal line group CK1 includes a clock signal line CK11 and a clock signal line CK21, the second clock signal line group CK2 includes a clock signal line CK12 and a clock signal line CK22, the third clock signal line group CK3 includes a clock signal line CK13 and a clock signal line CK23, and the fourth clock signal line group CK4 includes a clock signal line CK14 and a clock signal line CK 24; also, each switch group element 170 includes a first switch element 1721 and a second switch element 1722. The first switch element 1721 and the second switch element 1722 are of different types, the exemplary first switch element 1721 is an N-type thin film transistor, and the exemplary second switch element 1722 is a P-type thin film transistor. The embodiment adopts the P-type thin film transistor and the N-type thin film transistor to form a switch group element, so that the threshold loss caused by the transmission of low level and high level of the P-type thin film transistor is overcome; the N-type thin film transistor has no threshold loss when transmitting a high level and does not have a threshold loss when transmitting a low level. In this embodiment, a P-type thin film transistor and an N-type thin film transistor are selected to form a switch group element, so that the effect of no threshold loss can be achieved when high and low levels are transmitted.

It should be noted that there are various connection relationships between each clock signal line group and the switch group elements, and an exemplary one is shown, as shown in fig. 15, and a driving manner is introduced according to the structure of the display panel shown in fig. 15, as shown in fig. 16, which is another timing diagram of the display panel provided by the embodiment of the present invention,

the driving method of the display panel is specifically described as follows:

when the display panel works, the polarity inversion period of the display panel is still used as two adjacent frames.

During the on time of the first gate line, which corresponds to the first sub-period G1, during the first period t1, the clock signal line CK11 and the clock signal line CK21 are turned on, and the first terminal and the second terminal of the first switching element 1721 electrically connected to the clock signal line CK11 and the second switching element 1722 electrically connected to the clock signal line CK21 are turned on, so that the data signal with positive polarity output by the first data output terminal 191 is transmitted to the corresponding pixel; the second time period t2, the third time period t3 and the fourth time period t4 are similar to the first time period t1 and will not be described herein again. When the first period t1, the second period t2, the third period t3 and the fourth period t4 are completed, the scanning of one gate line is completed. In the turn-on time of the 2 nd gate line, the corresponding time is the second sub-period G2, and the working mode of the clock signal line is the same as the working mode of the clock signal line when the first gate line is turned on, which is not described herein again. It should be noted that, if the display panel includes i gate lines, after all the i gate lines of the display panel are scanned, the time period is a frame time. In the current frame, for the same color pixel, the polarity of the partially received data signal is positive, and the polarity of the partially received data signal is negative.

In the next frame, i gate lines included in the display panel need to be scanned, the scanning mode is the same as that of the previous frame, except that the polarity of the first data output end 191 of the previous frame is changed from positive to negative, and the polarity of the data signal output by the second data output end 192 is changed from negative to positive. When two adjacent frames of pictures are switched, for the same color, part of received data signals are changed from positive to negative, and part of the received data signals are changed from negative to positive, so that the flicker phenomenon is avoided, and the picture quality is improved.

It should be added that no matter which row of gate lines is scanned, a data signal with positive or negative polarity is transmitted to the corresponding pixel only when the corresponding clock signal line and the corresponding data output terminal are both turned on.

In one embodiment, as shown in fig. 15, the first color pixel 1011 and the third color pixel 1013 on the first pixel column 1301 are repeatedly arranged in the column direction, the second color pixel 1012 and the fourth color pixel 1014 on the second pixel column 1302 are repeatedly arranged in the column direction, the third color pixel 1013 and the first color pixel 1011 on the third pixel column 1303 are repeatedly arranged in the column direction, the fourth color pixel 1014 and the second color pixel 1012 on the fourth pixel column 1304 are repeatedly arranged in the column direction, and the four pixels in the same row have different colors in the first pixel column unit 131 and the four pixels in the same row have different colors in the second pixel column unit 132, so that the color mixing uniformity of the display panel is improved.

Further, the first color pixel 1011 is a red pixel, the second color pixel 1012 is a green pixel, the third color pixel 1013 is a blue pixel, and the fourth color pixel 1014 is a white pixel. In the embodiment, the white pixels with higher light transmittance are selected to improve the light transmittance of the whole display panel; further, when a screen with the same brightness is displayed, the power consumption of the display panel can be reduced. In addition, in combination with the above embodiments, in the same row, since the colors of the four pixels in the same row are different in the one pixel column unit 131, and the colors of the four pixels in the same row are different in the second pixel column unit 132, that is, every two adjacent pixels in the same row with the same color are separated by three pixels with other colors, an exemplary red pixel is taken as an example, and the red pixel with the shortest distance to the red pixel in the first pixel column unit is located in the second pixel column unit adjacent to the same row, and the green pixel, the blue pixel and the white pixel are separated in the middle. It can also be understood that, in the row direction, the red pixels, the green pixels, the blue pixels and the white pixels are arranged in a cycle manner, so that the pixels with the same color are prevented from being too close to each other in the row direction, the color mixing uniformity of the display panel is further improved, and the display effect is improved.

Further, the opening area of the white pixel may be smaller than the opening areas of the red, green, and blue pixels. The light transmittance of the white pixel is higher than that of the pixels with other colors, so that the opening area of the white pixel is smaller than that of the pixels with other colors, the light transmittance of the pixels with different colors is balanced, and the obvious brightness difference is avoided particularly in the pure color picture change process.

In addition, the white pixel has a smaller opening area, and the corresponding charging time is shorter, so that the power consumption of the display panel can be reduced.

In one embodiment, as shown in fig. 1, the display panel 100 in this embodiment may be a liquid crystal display panel. The structure and display principle of the compound are described in the relevant description above.

As shown in fig. 17, which is a schematic structural diagram of a display device according to an embodiment of the present invention, a display device 500 includes the display panel 100 according to the embodiment. It should be noted that fig. 17 only exemplifies a mobile phone as the display device, but the display device is not limited to the mobile phone, and specifically, the display device may include, but is not limited to, any electronic device having a display function, such as a Personal Computer (PC), a Personal Digital Assistant (PDA), a wireless handheld device, a Tablet Computer (Tablet Computer), an MP4 player, or a television.

The display device 500 in this embodiment includes the display panel in the above embodiments, so that the display device can also realize all the functions of the display panel. Also, the display device may have the following advantageous effects:

the data signals received by the pixels of the same color can be changed into the second signals from the first signals, the other part of the received data signals can be changed into the first signals from the second signals, the first signals and the second signals are signals with opposite polarities, so that the phenomenon that when two adjacent frames of pictures are switched, the data signals received by the pixels of the same color in the whole picture are flickering due to the fact that the brightness is different obviously caused by the fact that the polarity is changed to the other polarity is avoided, and the display effect is improved.

Compared with the prior art, the embodiment provided by the invention avoids the flicker phenomenon when the data signals received by the pixels of the same color in the whole display area are all changed from one polarity to the other polarity when the two adjacent frames are switched, and improves the display effect. And when the display panel is inverted, namely when the display panel is from a polarity inversion first time period to a polarity inversion second time period, in the display panel, one part of the pixels of the same color is changed from the first signal to the second signal, and the other part of the pixels of the same color is changed from the second signal to the first signal, so that the flicker phenomenon caused by the fact that the signals received by the pixels of the same color are all changed from one polarity to the other polarity in the whole picture is avoided.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
